The fall of Fort Fisher was really the death knell of the Confederacy, even though the cause was essentially lost starting in July 1863 and picking up speed through 1864 and to this late date.
I have to believe that General Bragg should have done something to save the fort, especially with the landings above the fort. But, that was just Bragg being Bragg.. Too bad the Confederates didn't just let Whiting continue to command the District. My thought is that he would have done something more.
And, i have to wonder why Porter was so keen to have the Naval Column attack the fort, despite their lack of training. It is my thought that he was hoping to have his sailors capture the fort before the Army as that would make him even more famous, perhaps as much as Farragut..
Anyway. --Old B-R'er
